Firefighters extinguished a three-alarm grass fire that temporarily shut down a lane of Interstate Highway 780 in Vallejo Thursday morning, according to Vallejo fire officials and the California Highway Patrol.

Pinole resident Angie Porter and her 13-year-old son River took the ramp from I-80 to I-780 toward Benicia last Thursday morning when they saw the dog being dragged on the side of a black truck with tinted windows.
